Claims (1)

[Scope of Claim for Utility Model Registration] At the inner circumference of the distal end surface, an inner sealing means is provided on a part of the outer circumferential surface by extending toward the distal end so that the connecting tube can be fitted into the outer circumferential surface and sealed on the inner surface. a joint body having an insertion tube portion and forming a connection flow path within the insertion tube portion; and a joint body concentrically and integrally coupled to the joint body,
A guard stopper member that has a fixed inclined cam surface whose inner diameter gradually decreases toward the tip end formed on one part of the inner circumferential surface, and a guide groove that passes through both the inner and outer circumferential surfaces in the axial direction on the other part. and a movable inclined cam surface which is fitted into the guard stopper member and whose diameter is made slightly smaller than the fixed inclined cam surface in one part of the outer peripheral surface and which is slidably engaged in the guide groove in another part. A passive convex portion guided by the connecting tube is formed on each of the connecting tubes, and a pressure restraining surface is formed on the inner circumferential surface, the inner diameter of which is approximately equal to the outer diameter of the connecting tube, and which retains and restrains the outer diameter surface of the connecting tube. A plurality of slit grooves are cut alternately from the proximal end side and the distal end side at appropriate angular intervals, thereby reducing the relative diameter of the inclined cam surfaces as they slide against each other. a retaining member that enables restoration to the original state; and a release device that is provided with an actuating means that is slidably fitted into the outer peripheral surface of the guard stopper member and that operates the passive convex portion from the retaining and restraining position to the releasing position. 1. An automatic coupling device for connecting tubes, characterized in that it is configured by comprising:
